In praise of slowness

· 650 words · Viewed ~237 times


A digital watch.

Sometimes - only sometimes - slowness is a feature, not a bug. A few weeks ago, I was reading about a purported use for "smart contracts". If your plane is cancelled, a smart-contract could automatically pay out your travel insurance, the millisecond the cancellation was reported. Nifty, right‽ Slowness for crap reasons There are plenty of processes which are slow for annoying reasons. The i…

Transferable Bank Accounts

A tiny lego Storm Trooper eats a chocolate coin.

Here's a (possibly) daft idea. What if you could pay for goods using a transferable bank account? Say you want to pay a friend some money. But you're not physically close enough to hand over cash. You create a new bank account with a unique username and password. As quickly and easily as getting a new email address. Couple of clicks and it is done. You move money from your main account into…

Should you use Let's Encrypt for internal hostnames?

A padlock engraved into a circuit board.

Julien Savoie has written a brilliant post explaining how you can enable https on your intranet. This is useful for several reasons. It means your employees aren't constantly fighting browser warnings when trying to submit stuff internally. All your http traffic is encrypted. You don't need to install a self-generated root certificate on devices. Lovely! But there's a downside. Every TLS…

DVD review: Doctor Who - Shada

· 1 comment · 400 words


The Doctor and Romana stare at a grey orb.

This is the semi-mythical "lost" serial from Doctor Who. Written by Douglas Adams at the height of his powers, and cruelly lost to an industrial dispute. There have been many attempts to recreate the show - but this is the definitive edition. All the missing sequences have been animated - with the original cast providing their voices. And what a show it is! The dialogue is sharp - rarely a…

Book Review: The Empyrean by Katherine Franklin

· 1 comment · 300 words


Book cover with a glowing green planet.

Palia’s emotions are in turmoil. After watching her son succumb to Empyrean fire, she barely escapes the same fate. Guilt ridden and alone, she will not stop until his killer is brought to justice. The Protectorate forbids Ferrash to have emotions. That suits him, since he cannot avoid the people who control the Empyrean. Making this sacrifice prevents them from hijacking his feelings and using …

A novel method of faster than light communication

A digital watch.

(I *sure* this was the basis a short story I read - but I can't find it. So I'm (re)writing it. If you know of the original, please let me know…!) The speed of light is a universal constant. This "speed limit" is fundamental to everything we understand about physics. Information - when propagated via the electromagnetic spectrum - cannot travel faster than 0.3 Gigametres per second. There is no a…

DVD Review: Delta and the Bannermen

· 500 words


DVD cover for Doctor Who's Delta and the Bannermen.

This is not one of the best Doctor Whos. But it is fascinating as a template for New-Who. A cold open on an alien planet! A celebrity comedian cameo! A feisty female companion! Wales! On paper, Delta contains all the ingredients for a great serial. What if all the weird people at your holiday camp are weird because they're aliens?!!? Is that bus really a spaceship? What if your best friend's…

Goodbye daily blogging

· 2 comments · 400 words


A calendar view of all my blog posts in the last three years.

At the start of 2020, for some strange reason, I decided to publish a new blog post every single day of the year. And, a third of the way through that, COVID struck. In a way, it was good for my motivation. I didn't have any fun and exciting trips to go on - so I had plenty of free time. But there's only so long you can stare at four walls while your friends are sick and dying, without going out …

Movie Review: Ammonite

· 200 words


Movie poster, two women's faces overlayed on each other.

What a treat of a movie! Kate Winslet shows, once again, how great acting isn't about who can shout the loudest, but who can convey the most meaning through a single glance. It is a movie of delightful contrasts - the sound design is overpoweringly loud, until it suddenly disappears. The silence is rarely punctuated with anything so crude as dialogue. In a way, the sex scenes feel not…

Certified Blockchain Professional - Module 1

Logo for the Certified Blockchain Professional.

As previously discussed, I'm doing the Certified Blockchain Professional course. It is self-directed learning, so I'm going through it at my own pace. In order to consolidate my learning, and help organise my thoughts, I'm blogging about my reflections on each module. These are mostly notes to myself - but I hope if you find something interesting (or incorrect) that you'll leave a comment. …

Logo for the Certified Blockchain Professional.

Why do I do this to myself? Why? As part of my ongoing MSc, I have to take 3 professional training courses. I've completed my cybersecurity course, and I have a Machine Learning course booked for January. So what to do next? There's a lot of discussion in government circles about Blockchain. As with any new tech, there are plenty of Thought Leaders™ and sales drones trying to push it. For e…

Quick and dirty way to rip an eBook from Android

Unix is user-friendly — it's just choosy about who its friends are.

I recently purchased a book for my MSC which was only available via a crappy Android app. There was no obvious way to decrypt it to read on a more sensible device, so I resorted to the ancient art of screenscraping. This is a quick-and-dirty way to grab images of the pages and convert them to a standard PDF using Linux. There's a lot more you can do to make the end book more useful, but this'll…
